With this store, turn your terrace into a real living room, bright and temperate. In motorized version, a simple action on the remote control is enough to maneuver it.
Cost: 3,500 € placed (5,96 x 4 m, with acrylic fabric of 320 g)
Time: 1 day to 2 or 3 people (depending on size of the blind)
Equipment: 1 ladder per person, pencil, spirit level, meter, chalk line, hole punch, screwdriver, pipe wrench, allen wrench
At the maneuver
In its "basic" version, the operation of the blind is done manually by operating a crank completed by a hook. More comfortable, a motorized version team many models (very discreet system because powered by a tubular motor, integrated directly into the winding bar). The startup is done either by a wall switch placed inside the home, or by a remote control.
If the awning is a valuable ally to regulate the temperature of the room which it hides the bay window, you are not always present to ensure the maneuver. Hence the interest of the automatic control system: when the sun is intense, a photosensitive cell triggers unwinding. In case of strong wind, the anemometer immediately sends the order of withdrawal to the mechanism.
Simple and efficient
The awning allows to live in harmony with the sun. The principle of operation is simple: the winding bar unwinds the fabric, driven by a load bar that projects outwards, supported by a pair of articulated arms.
The projection blind
To guide the movement and deploy the canvas, the system uses highly resistant articulated arms. These arms (called "invisible") support the load well and can be deployed far enough from the winding bar (4 m for our example). They do not interfere with the lateral passage under the awning, when it is lowered quite low. By adding the weight of the load bar, that of the fabric and also the impulse of the springs integrated at the start of the arms, the projection drives the fabric which remains well tensioned during the maneuvers.
The various manufacturers most often opt for anodized or lacquered aluminum frames. In the same way, they leave cotton fabrics for rot-proof textiles in 100% acrylic drummers or in PVC-coated glass threads (Screenglass).
Although stripes still represent a large portion of sales, there is a wide range of colors and patterns. If you prefer plain, be aware that darker shades absorb more light than light colors and they also deteriorate more quickly under the effect of ultaviolet.
Which model to choose?
The "first prices" do not have a protection box against bad weather and dust when the fabric is rolled. Then come the models with a simple chest or "cassette" that protect the canvas on top, but leave the bottom in the open air.
Finally we find the blinds with integral trunk: a kind of waterproof fairing in aluminum that offers protection of arms and canvas (our example: model "Corfu" Storistes de France, equipped with a Dickson Constant acrylic canvas 320 g ). Only then exceeds the lambrequin (headband), which can be slid sideways to remove the time of wintering.
Lay the blind yourself
Before placing your order, note the length and width of your terrace (or balcony), as well as the available height of the wall on which the awning must be fixed. The more the fabric has to project away from the wall (4 m for example), the higher the attachment must be to prevent the end of the awning (load bar and valance) from coming too close to the floor. No way to bang your head against the bottom of the blind!
In general, the blind has an inclination of the order of 15° and it is necessary to reserve a space of about 25 cm above the openings (example: flaps). With a simple string and a sheet of paper folded to form a 15° angle, you can do a projection simulation and check that you have sufficient height. No need to try to place the blind too high because the shadow of the canvas would be less important.
Whether it is a blind provided by a craftsman or a personal purchase, it is made to measure and delivered ready to mount with brackets (but not the anchor that depends on the nature of the wall).
Heal the bindings
To install it yourself, simply use the brackets, locate the piercing points and peg all together securely. It is often at this stage that we discover the exact nature of the wall (it can vary from one hole to another). Anchor bolts or lag bolts associated with anchors for solid masonry, chemical sealing when faced with hollow walls (bricks or blocks).
Once the consoles fixed, the support bar of the blind must come engage on it. On each support, a bolt is responsible for blocking the bar.
If you opt for a motorized version, connect to a power supply protected by a 30 mA differential circuit breaker. The switch is usually installed inside the house, near the bay window. Our realization is satisfied with the only remote control.
Locate the location of the consoles
Our blind measuring nearly 6 meters long, five wall consoles will distribute the load. Evaluate the height with respect to the ground taking into account the projection and raise the central axis of the high level.
Take into account the openness
The two consoles on each side of the support bar should be on either side of the arm's articulation point without obstructing the opening. Take this into account when locating.
Ensure the nature of the support and the quality of the anchor
It is at piercing that we often discover the nature of masonry. Here, some fastening points meet hollow partitions (breeze blocks) and others only cross concrete.
For a chemical seal, blow hard into the hole to drive off the dust (blower of a compressor or single end of pipe), then place the sieve in the hole.
Garnish with resin
Inject the resin until the filling is complete and fill the entire cylinder. On this model, the plastic crown is folded down to reduce the orifice to the diameter of the threaded rod.
Insert the threaded rod
Engage the threaded rod without waiting. It will repel the product through the sieve, in the cavities. Push gently until you feel about 2 cm.
Solid or hollow materials: with or without installation time
In a solid masonry, lag bolts and dowels are sufficient. Where you install a chemical seal, wait for the setting time (2 hours for an ambient temperature of 20° C).
The electrical connection must be as discreet as possible, inside the house. An angled hole makes it possible to place the connection box behind the curtain along the bay window.
Locate the fixing holes
It is more practical to locate center console mounting holes with string tied between the end brackets. Here, five consoles are enough to support the weight of the blind.
Put the chest
The integral cassette awning is equipped with a complete rollover. Present the blind in front of the consoles and engage the support bar. Only the hood of the bottom will be added at the last moment.
Secure with pins and bolts
Once the square tube of the support bar is at the bottom of the brackets, install the bolt-bolts and tighten securely. These bindings will then be hidden by the bottom cover.
Adjust the height of the awning deployed
Once the awning is attached and connected, press the remote control to operate the descent. Let go down completely to check if the height under the canvas suits you.
Change the slope of the blind
The point of articulation of each arm has a tilt adjustment of the blind. To modify it, relieve the weight of the awning by lifting it with one hand and use the tilt bolts.
Fix the lower cover of the formwork
Feel free to spend some time for the setting. You must be able to walk under the canvas without bending your head. Finally, fix the long hood that closes the underside of the formwork.
Install an anemometer
On this model, the installation of an anemometer completes the connection to the sector of the engine. When the force of the wind exceeds a certain threshold (adjustable), it actuates the ascent. The anemometer is adjusted using a screwdriver. placed on the top of the housing, a photosensitive cell activates the projection of the blind when the sun shines.
